VEVOR 3-Jaw Lathe Chuck, 6 Inch (160 mm), Self-Centering Chuck with 1 1/2 in-8 Threaded Backing Plate, 0.12-5.71 in (3-145 mm) Clamping Range with T-wrench Screws, HT300 Material, for Wood Metal Lathe

Excellent runout been a machinist 45 year and was very surprised how good the runout was quality is very good

Seems to run within .002, but the instructions clearly state that if you remove the jaws make sure, they are put back starting with Number one and put them back in their number sequence. Problem is there are no numbers on the jaws or the chuck. UPDATE. I found the numbers on the jaws, but there were not any on the chuck, so I engraved the numbers on the chuck, now's all good. The last test after cleaning the inside of the chuck shows one- and three-quarter thousand's total runout. It doesn't get any better than that with a three jaw self-centering chuck unless you play around with shims. Fantastic chuck at any price. I highly recommend it .

Idk what I expected for the price, but they did a bad job of finishing this chuck. It required a full disassembly and deburring and clean out of the box to run properly. And even once that was done, it typically only held concentricity as well as 5 thou most of the time. Other than that it functioned completely fine as a chuck. For the price I don't know if I could have expected any better.

I received a VEVOR 6 in lathe chuck but the backing plate is the wrong size. It should have a 1 1/2 in-8 Threaded Backing Plate but it came with an <<< INCORRECT>>> 1 3/8 in-8 Threaded Backing Plate. I have not heard a response from the Vevor product support group yet. If I do not heard from VEVOR then I will cancel the Amazon VEVOR order and get an Amazon CME lathe chuck with an attached backing plate.

The 1 1/2-8 threads were terrible. They were so bad they almost look like they were cast and not machined. I wouldn't put this on my lathe for fear of destroying the headstock threads. I've had good luck with past Vevor purchases so I'm assuming that this might be a one-off misfit.

Era o que pretendia

Naja...eigentlich war zu erwarten, dass es nicht direkt aus dem Karton montierbar war. Die Adapterplatte passte gar nicht zur Drehmaschine und die vorhandene nicht zum Futter, da der Lochkreis um 4mm differierte. Aber M8 Schrauben zur Befestigung waren mir dann doch nicht ganz geheuer, so dass ich zur vorhandenen Adapterplatte M10 Gewinde ins Futter geschnitten habe. Der Rundlauf geht mit 2,5/100mm in Ordnung. Aber wie ein Vorredner schon schrieb, das Teil muss komplett zerlegt werden. Grate entfernen, neu fetten und die Backen nachbearbeiten, damit sie auch schön leichtgängig sind. Für diesen Preis für einen Chinartikel hätte ich mehr Sauberkeit und Präzision erwartet. Sei's drum...immer noch deutlich günstiger als ein Röhm, mit 2,5/100 ausreichend Rundlauf, aber man muss erstmal Hand anlegen, um es zu verwenden.

Hola el producto es excelente Buenas calidad y ajuste. Venía Un poco sucio y con algunas rebabas del mecanizado, nada que no se pueda solucionar con un poco de bricolaje y engrase. La tapa trasera de plástico rozaba un poco en los piñones,También hubo que ajustarla Por eso no le pongo 5 estrellas. Es un buen producto por ese precio

I had read the unit some other buyers got had burrs everywhere. Mine came clean. No burrs. A very nice chuck. Quite accurate. The only thing they should do is make the back plate thicker to accommodate flush mounting the socket head fasteners to hold it to the chuck. That way there would not be any protruding bolt heads.

Mine came full of metal grindings take apart and clean completely. The jaws work but need some fine tuning. Looks nice though. Has an oiler port. Is not stamped for jaw placement.
